Research Abstract |
Submicron-scale structures of natural omphacitic pyroxenes in high-grade blueschists and low-temperature hydrous eclogites were examined using high resolution microscopy and laser Raman spectroscopy. This study confirmed that the anti-phase domain size of undeformed omphacite within garnet porphyroblast had high potential for geospeedometer. However, inorder to apply this method, further understanding of disequilibrium growth of omphacite and garnet in low-temperature metamorphic rocks are required.
